I'm on a Win64 machine and compiling Win32 works fine. I'm using Visual Studio 17 Community with Visual D. DMD is up to date as is Visual D.

I added a x64 "solution platform" to the configuration manager which added a -m64 flag to my linker options. I'm not sure what else I'm meant to do to get it to compile as x64?
